Hair coloring method comprising an ethylenic phosphonic polymer and a pigment

The present invention relates to a hair coloring process using a pigment and an ethylenic polymer containing a phosphonic acid group.

In the field of dyeing keratin fibers, it is already known to color keratin fibers by different techniques from direct dyes for non-permanent dyes or dye precursors for permanent dyes.

Non-permanent coloring or direct coloring consists in dyeing the keratin fibers with dye compositions containing direct dyes. These dyes are colored and coloring molecules with an affinity for keratin fibers. They are applied to the keratin fibers for a time necessary to obtain the desired coloration, then rinsed off.

The conventional dyes which are used are in particular dyes of the nitro benzene, anthraquinone, nitropyridine, azo, xanthene, acridine, azine, triarylmethane type or natural dyes.

Some of these dyes can be used under lightening conditions which makes it possible to obtain visible colorations on dark hair.

It is also known to dye keratin fibers permanently by oxidation coloring. This coloring technique consists in applying to the keratin fibers a composition containing dye precursors such as oxidation bases and couplers. These precursors under the action of an oxidizing agent will form one or more colored species in the hair.

The variety of molecules involved in the oxidation bases and couplers, allows obtaining a rich palette of colors and the resulting colorings are generally permanent, powerful, and resistant to external agents, in particular to light, bad weather, washing, perspiration and friction.

To be visible on dark hair, these two dyeing techniques require prior or simultaneous bleaching of the keratin fibers. This bleaching step carried out with an oxidizing agent such as hydrogen peroxide or persalts leads to a non-negligible degradation of the keratin fibers which alters their cosmetic properties. The hair then tends to become coarse, more difficult to disentangle and more fragile.

Another coloring method is to use pigments. Indeed, the use of pigment on the surface of keratin fibers generally makes it possible to obtain visible colorations on dark hair since the pigment on the surface masks the natural color of the fiber. The use of pigment for coloring keratin fibers is for example described in patent application FR 2 741 530, which recommends the use for the temporary coloring of keratin fibers of a composition comprising at least one dispersion of particles of film-forming polymer comprising at least one acid function and at least one pigment dispersed in the continuous phase of said dispersion.

The colorings obtained by this mode of coloring have the disadvantage of being eliminated from the first shampoo.

It is also known from patent application FR 2 907 678 to carry out colored sheathings of the hair from a composition comprising a polysiloxane / polyurea block copolymer and a pigment. However, with such a composition, the sheaths obtained are not always very homogeneous and the individualization of the hair is not always very good.

It is also known from patent EP 1 392 222 to use a cosmetic composition for the care and / or treatment of keratin materials comprising a supramolecular polymer comprising a polymer backbone and at least two groups capable of forming at least three hydrogen bonds, and of patent EP 1 435 900 to use a hair composition comprising a supramolecular polymer comprising a polymer backbone and at least two groups capable of forming at least three hydrogen bonds and a surfactant or a hair conditioning agent.

Thus, the object of the present invention is to provide a composition for coloring keratin fibers, such as the hair, which makes it possible to obtain colored sheathings having good resistance to aggressions such as brushing, not bleeding, resistant to sweat, light and weather, remanent to shampoos and various aggressions that the hair can undergo without degradation of the keratin fibers and while maintaining perfectly individualized hair
